Introduction to aCVi

aCVi is SingMai's proprietary method for the long distance transmission of high definition video.

aCVi can transmit high definition non-compressed video across more than 300m of coaxial or twisted pair cable or via RF transmission, with near broadcast quality, and longer distances with some small signal degradation.

aCVi has very low latency, is secure, and also supports bidirectional data transmission and power over coax.

aCVi is available as two intellectual property cores for incorporating into your own product,

an encoder (transmitter) core, PT56, and a decoder (receiver) core, PT52.


aCVi is also available as a transmitter module (DB06) and receiver module (DB08).
